Be it known that I, LEONARD 0. PILLs- BURY, a citizen'of the United States, resid- This invention is aniimprovement on that samebolts employed in assembling the Wheel ing. at Crocker,"'in the county ofClark and State of South Dakota, have inventednew and useful Improvements inMud -Pul1er Fastenings, of which 'the following is a specificatio.

shown'in my copendingapplication, Serial 691,249, filedAprillG, 1912, and has for its 'especial objects the improvement of the manner'of attachment and to 1 make the drum readily applicable'to wheels of any size without change'of construction, either of the wheel or my 'appliance as supplied;

As is well known the usual wheel construction generally employed. at this time includes a hub' having two flanges between which the spokes are held, the 'i'langes'being bolted firmly against the spokes by means of bolts engaged therethrough and having respective nuts thereon outwardly of one of the It is my purpose to enable the use of the I to hold my puller in'place; Further, as the assembling bolts of large'wheel hubs are spaced in a greater circle than on small wheels, it is my purposeto provide means 1 to enable the adjustment of the two-way slots of my first construction to suit the needs of the individual customers purchasing the appliance. I l Additional objects and advantages will be apparent, someof them being understood I from the followingdescription and from the drawings, in which,

' Figure 1 is a side viewof a wheel equipped withmy invention, Fig.2, is a fragmentary sectional View of a hub and part ofa wheel, with my invention attached, Fig. 3 is a back view of my drum with the adjustable quickdetachabledevices in place, F ig.- 4 is an edge view of the hub with my device attached, Fig. 5 is a perspective of the special nut for the-hub, interchangeable with the regular nut on the assembling bolts.

There is illustrated a wheel 10 of familiar construction,including the hub flanges l1 and 12 between which are confined the spokes'13in the usual manner, the bolts 14: engaged through registered apertures in the flanges and through the spokes and having the nuts 15 of ordinary form engaged with 'certainof the bolts and nuts 16'to be de- Specif cation of Letters Patent.

of'thehub. In orderto permit the attachfment of my present device with rapidity and adapt the wheel therefor with a minimum of labor, I supply therewith the nuts 16, three of which are engaged with equally spaced bolts in the hub, the original nuts being first removed,-and the bolts drawn from the front side of the huband inserted from the back side, so that my special nuts may be located at the outer side of the Wheel these nuts are equally applicable to use with the form of my invention shown in my previous applicationabove mentioned. I provide a drum 17, whichmay be similar to that described in -my'said copending application, or any other suitableconstruction including an attaching flange adaptedto be disposed parallel to the'planeof the wheel to which it is to be attached, and closely thereadjacent.

In this instance, I form the attaching flange 20 in the form of an annulus of sheet metal, and the drum proper is formed of another piece pressed to form the peripherally recessedannulus 21 the inner sideof which is secured to'the flange 20 by rivets, or other- The flange is of somewhatgreater diameter than the drum proper, as shown wise.

though these proportions are not arbitrary and it may not be found necessary in practice to make theflange so large-and it projects inwardly so as to accommodate the device to the smaller hubs to which it is to be attached, while yet allowing proper clear ance' for the reception of the outer parts of the larger hubs upon which it may be required. I I I The drumannulus 21 may be formed from pressed metal or cast, as most desirable. Equally spaced around the flange 20, there are three pairsof slots 22, parallel to ,re spective radii of the flangeand on each side thereof; These slots are shown opening on the inner edge of the annulus, but may be closed thereat if desired, this being a mechanical detail of construction not considered essential to illustrate. Where the slots'pass close to thefiange of the drum, the drum is provided with alined slots 23 wider than those 22 to permit'the free. passage thereunderof the heads 2e 'of bolts 25 the stems of whicharedisposed slidably in the-slots 22.

These bolts carry the attaching blocks which are engaged thereon in a suitable manner, to be held" against the, annulus by t nuts 26 screwed upon the bolts. Thus the blocks maybe held adjustablycn' the an --nulus and secured at any distance fromitsi I a center. Each o f the blocks 25 comprises I two plates, an inner one 27 next-the annulus, .and an' outer one 28.

' 0 one has simply an enlarged slot 29'therein V intermediately of the slot, and being sufficoncentric with the annulus when. adjusted ciently large tovclear Well theheadlOIon thenut 1 6 whenthe drum is positioned on the wheel. The'wplate 28 is provided-with a "slotf30 similar to that in my first.R'Dplicati n befOre J mentionedoperatingflfor the same purpose.

' Thelslot 30 is sufficiently large, at themiddle to freely receive the head 4:0;therethrough,

but is reduced at each end so that movement of the nut toward either end will cause the reduced part of the slot to engage under the head, as willbe described. The inner sides:

of these reduced parts of- ,t he islotBO. are preferably nearly concentrlc wlth the annulus atapoint near the inner'endsiofthe slots22, and the outer sides concentricw th the annulus at ,a point adjacent the{ outer ends of the slots 22, so th'atjat anypoint in J the adjustment of the -device,itjwill be free 7 to rotate ineither direction forready engagement of the reduced parts of the slots around, the nuts 16 as will be described; 1-

The nuts- 16 each comprise the enlarged hexagonal'nut base 31, by which, they are adapted 130 ;be screwed into place tightly with little difliculty, outwardly from which there,- extends the reduced neck 82, carrying the head 40' before, mentioned. The neck of theplate-27, and the neck is sufliciently groove 33 aroundthe nut .to allow full engagement of the sides ofthe reduced parts, of* the slots 30 under the headat any radius ofadjustment of the blocks25 The clearancebetween the head 40 and thebase 31 is slightly greater than the thiclmess ofthe i :In-use,when the device is purchased, the nser removes the assembl ng nuts from three equally, spaced flange boltsof'the hub, takes out, the bolts and inserts them, from the inner sideof thehub, and engages the nuts l6 thereon-as shown. The distances between thel cent'ers of the readjusted bolts then beingitaken, the blocks 25are adjusted with I i f thecenters ofthe, enlarged parts of the slots 30, correspondingly spaced, and'thenuts 26 properlytightened. The measurement may be" obviated'by leavingrthe -nuts 26 slightly The inner.

then adjust the whole device on thehub by tappingwitha hammer or other object until the "annulus" 21' is concentrically spaced around the projecting barrel, of the :hub. The nuts 26 may then be tightened, and the device removed by rotating the drum on the wheel until the enlargements of the slots 30 permit its withdrawal The: device is normall; carried in the tool 7 box of the vehicle, and Whenreq'uir'ed for i use, is simply presented against thewheel around the'hub so that the slots 30 pass over ,fthenu'ts; 16, and rotated slightly in the, op-
